Definitions

  • Such a seeder is for example by the EP 1 704 764 A1 known.
  • a rotatably arranged singling drum is provided, in which the perforations are arranged in rows of perforations. Seeds attach themselves to these perforations if the perforations subjected to a pressure difference are passed through a seed stock.
  • a covering the pressure applied to the perforations covering device is arranged.
  • one end of a discharge duct is arranged on the side of the drum on which the seeds adhere to the perforation.
  • the end of the discharge line is arranged with its mouth opening at least approximately reaching up to the drum surface.
  • the junction area of the discharge line is designed as a vertical section to the longitudinal center line of the discharge line.
  • the invention has for its object to improve the junction area of the discharge line with respect to the introduction of the seeds and to optimize fluidically.
  • the Ausbring ist has in its junction area and / or to heranichenden to the drum surface end portion on its outer circumference on a circumferential chamfer-like approach that the chamfer-like projection is convex on its outer surface.
  • the discharge lines each with a on the metering of the metering and / or separating member attached by means of a fastener mouthpiece to the metering and / or separating member for receiving the metered and / or isolated seeds are connected.
  • the mouthpiece thus forms the transfer point of dosed by the dosing and separating member and separating seed grains in the leading of the separating and / or dosing to the seed storage facilities Ausbring effeten.
  • a particularly advantageous embodiment of the housing and mouthpiece is achieved in that the housing and the mouthpiece are integrally formed.
  • each Ausbring Vogel sensor elements are assigned.
  • a simple arrangement of the sensor elements can be achieved in that the mouthpiece is arranged on the housing receiving the sensor elements.
  • a particularly simple arrangement of the housing for receiving the sensor elements is achieved in that the mouthpiece is integrated into the housing receiving the sensor elements.
  • the fastening elements are designed for fastening the mouthpiece as the housing receiving the sensor elements.
  • the reservoir is designed as a pressure-tight container that by means of a blower, the interior of the container and the outside of the drum in their attachment area for the seeds to the perforations with an overpressure to produce the pressure difference can be acted upon, and that the initial areas of the discharge lines are in communication with the reservoir.
  • the drill has the reservoir, not shown, which opens into the housing 1. Below the reservoir is located in the housing 1, the rotatably mounted and rotating driven singulating drum 2. In the circumferential surface of the singling drum 2, the perforations, not shown, are arranged in circular circumferential rows of perforations.
  • the storage tank and the housing 1 above the drum 2 are closed at least approximately pressure-tight by means of a lid, not shown.
  • the reservoir and the housing 1 above the drum 2 by the connected to the junction box 3 and not shown compressed air fan can be acted upon with compressed air, so that the rows of perforations with a pressure difference between the interior 4 of the singulating drum 2 and the outer region 5 of the singling drum 2 be charged.
  • the seed hopper or the housing 1 below the seed hopper, in which the singling drum 2 is mounted rotationally and sealingly, has the spaced-apart side walls 9, which extend parallel to the direction of movement 10 of the drum 2 and at least approximately sealingly cooperate with the drum 2.
  • the rows of perforations are assigned to discharge devices 11, which are designed as depositing devices, not shown, and which are arranged in a different manner.
  • the Ausbringletechnisch 11 are connected to mouthpieces 12.
  • the mouthpieces 12 are attached to the housing wall 14 of the housing 1, which encloses the singling drum 2 airtight.
  • the side walls 9 are connected to the housing wall 14.
  • the mouthpiece 12 has on the side facing away from the singling drum 2 an enlarged tubular portion into which the dispensing line depicted as a hose is inserted and clamped in the mouthpiece via a hose clamp 17 placed on the end 16 of the mouthpiece 12 becomes.
  • the separating drum 2 facing region 18 of the mouthpiece 12 has an inner diameter which corresponds at least approximately to the inner diameter of the discharge line 15.
  • a housing 19 connects.
  • This housing 19 is designed to receive sensor elements for counting or detecting small particles which pass through the mouthpiece 12 or the dispensing line 11 from the singulating drum 2 in the direction of the seed depositing elements.
  • the housing 19 and the mouthpiece 13 are integrally formed, so that the mouthpiece 12 is integrated into the housing 19 receiving the sensor elements.
  • the mouthpiece 12, in which the sensor elements receiving housing 19 is arranged are integrally formed.
  • the roller formed as a roller, which is applied to the perforation pressure difference for detaching the seeds from the perforation interrupting cover 21 is arranged.
  • the end 22 of the discharge line 11, which is formed by the mouthpiece 1.2, is at least approximately close to the drum surface of the drum 2 in the area where the roller 21 of the cover device is arranged, introduced.
  • the discharge line 11 has a circumferential chamfer-like projection 24 on its outer circumference in its mouth region 23 or end region 22 reaching up to the drum surface.
  • This bevel-like approach is convex on its outer surface, as in particular the Fig. 3 shows. This is achieved as the Fig.
